Linear Approximation of Trimmed Surfaces
نویسنده
چکیده
Parametric surfaces in various representations, such as Bézier-and B-spline-tensorproduct patches, triangular patches etc., play an important role in CAGD-applications. Connecting patches with different degree of continuity and trimming surfaces are well-known techniques to construct a variety of shapes like ship hulls, car bodies, etc. For finite element analysis, stereolithography, rendering and other areas, techniques for approximating such surfaces by a piecewise linear set of elements (mostly triangles) are required. The aim of these techniques is to obtain a triangulation that

Topologically consistent trimmed surface approximations based on triangular patches
Topologically consistent algorithms for the intersection and trimming of free-form parametric surfaces are of fundamental importance in computer-aided design, analysis, and manufacturing. Since the intersection of (for example) two bicubic tensor-product surface patches is not a rational curve, it is usually described by approximations in the parameter domain of each surface. If these approxima...
متن کاملGPU-based Appearance Preserving Trimmed NURBS Rendering
Trimmed NURBS are the standard surface representation used in CAD/CAM systems and accurate visualization of trimmed NURBS models at interactive frame rates is of great interest for industry. To support modification and/or animation of such surfaces, a GPU-based trimming and tessellation algorithm has been developed recently. First, the NURBS is approximated with a bi-cubic hierarchy of Bézier p...

متن کاملEfficient Trimmed NURBS Tessellation
Interactive rendering of trimmed NURBS models is of great importance for CAD systems. For this the model needs to be transformed into a polygonal representation. This transformation can be either performed in a preprocessing step, at the cost of losing the capability to edit the surfaces, or on the fly during rendering. Since the number of frames per second is usually critical, efficient on the...
متن کاملRay Tracing Triangular Trimmed Free Form Surfaces
This paper presents a new approach to rendering triangular algebraic free form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides for quick identification of the surface regions likely to be hit by a ray. For each leaf of the hierarchy an approximation to the corresponding surface region is stored. The approximation is used to compute a good star...
